If 100 joules of work must be done to move electric charge equal to 4

1.	If 100 joules of work must be done to move electric charge equal to 4 C from a place, where potential is -10 volt to another place where potential is V volt, find the value of V.
Answer» Given: q₀ = 4 C, V_A = -10 volt, V_B = V volt, W_AB = 100 J To Find: Potential (V) Formula: V_B – V_A= \(\frac{W_{AB}}{q_0}\) Calculation: From formula, V – (-10) = \(\frac{100}{4}\) = 25 ∴ V + 10 = 25 ∴ V = 15 volt

If 100 joules of work must be done to move electric charge equal to 4 C from a place, where potential is -10 volt to another place where potential is V volt, find the value of V.

Answer»

Given: q₀ = 4 C,

V_A = -10 volt,

V_B = V volt,

W_AB = 100 J

To Find: Potential (V)

Formula: V_B – V_A= \(\frac{W_{AB}}{q_0}\)

Calculation: From formula,

V – (-10) = \(\frac{100}{4}\) = 25

∴ V + 10 = 25

∴ V = 15 volt
